The information you are about to explore is stored in “the cloud”. Over 8GB of data is available. You may use it for research and educational purposes but NOT for comercial intent without express written permission from the owners.

Wikipedia explains the concept of Cloud: “Cloud computing relies on sharing of resources to achieve coherence and economies of scale, similar to a utility over a network.  Cloud computing, or in simpler shorthand just “the cloud”, also focuses on maximizing the effectiveness of the shared resources. Cloud resources are usually not only shared by multiple users but are also dynamically reallocated per demand. This can work for allocating resources to users. For example, a cloud computer facility that serves European users during European business hours with a specific application (e.g., email) may reallocate the same resources to serve North American users during North America’s business hours with a different application (e.g., a web server). This approach should maximize the use of computing power thus reducing environmental damage as well since less power, air conditioning, rack space, etc. are required for a variety of functions. With cloud computing, multiple users can access a single server to retrieve and update their data without purchasing licenses for different applications.”

  Derek Butcher

Derek Butcher, of Adelaide, Australia, started in 1976 as a self professed “quasi-botanist,” working to unravel the intricacies of Bromeliacae. He is well known in Australia for his book, “An Amateur’s Guide to the Greyish Leaved TILLANDSIOIDEAE” to help interpret his favorite genus, and his checklist to keep order in the hybrids produced in his country.

He is the first Australian to have a Bromeliad species named after him – Puya butcheriana. This is now treated as a synonym of P. humilis but continues to survive in Selby Gardens herbarium  as a dried specimen. He also maintains the most comprehensive list of Bromeliad genera names, changes, and synonyms, stretching back to pre-Linnaeus!

From 1998 to 2008, Derek operated the “Cultivar Register” for the Bromeliad Society International (BSI) and loves nothing better than the challenge of piecing together “the story” behind any Bromeliad.

Says Derek: “1998 was when I really started transferring all my hard copy of Bromeliaceae data to my computer because I could easily share it with others. Nobody was likely to want the hard copy anyway even if it were mentioned in my Will!  As more and more information was made available by educational institutions on the internet this was checked and added to my files. The information gathered is too large to even consider publishing in book form. Just as others have freely given their information for educational purposes so too I hope others who refer to the data given here will be used for educational and NOT commercial purposes.” Let us honor his request and make  good use of his generous contribution.

I will soon upload more files covering other genera.
